Definitely buy a modem, especially since you already have the router in the Airport. Something like this will serve you well.
The only issue is that you do not want dhcp from both the modem (acting as a router) and the Airport. I am not sure how it is configured out of the box, but you may have to turn off the dhcp on the modem (which is easy from a web browser.)
